Aimee Copeland's fight for life: in darkest clouds, hope. Literally.

CARROLLTON, Ga. -- A phenomenal response for Aimee Copeland on Tuesday at her college in Carrollton resulted in more than 200 people offering to donate blood -- to save her life and the lives of others who need emergency blood transfusions in order to live.

Aimee Copeland, 24, is fighting a rare, flesh-eating bacteria, necrotizing fasciitis, which she contracted when she fell into the Little Tallapoosa River on May 1, during an outing with friends, and cut her leg.
